(please hurry) A moon of radius, Rmoon is orbiting a planet which has a radius, Rplanet. Given Rplanet plus the radius and the period of the moon's circular orbit, it is possible to calculate the A. acceleration of gravity at the surface of both the moon and the planet and the centripetal acceleration of the moon at its location. B. acceleration of gravity at the surface of both the moon and the planet. C acceleration of gravity at the surface of the planet and the centripetal acceleration of the moon at its location. D. acceleration of gravity at the surface of the moon and the centripetal acceleration c the moon at its location. E. acceleration of gravity at the surface of the planet. F. acceleration of gravity at the surface of the moon. G. centripetal acceleration of the moon at its location.
